i wanted to convert a integer range from -1000 and +1000  to 0 and 255 how to do it im a complete noob.

thanks.

You add and multiply.  Add 1000 to get your offset in the right place.  You will now have a range of 0 to 2000.  Now multiply by 255/2000 (I'll let you do the reduction).

Hi noob,

please define "convert"! Do you want to coerce or to scale?

Look at the comparison palette, there's a "In Range and coerce" function. You may use it to apply limits for your input integer:

another noobie question : how can you insert selected items from an unbundled cluster to a array of numeric indicators ? thanks.

Hi cyril,

you could use InsertIntoArray (if you really want to insert) or BuildArray (pre-/appending values)...

It seems a recommendation for this and that is needed...
